Key Features of the ABB REF615 Series
All REF615 relays share fundamental characteristics,regardless of their specific configuration code:
Comprehensive Feeder Protection:They offer a wide array of protection functions to safeguard feeders from various faults.These include:
Overcurrent protection:Both directional and non-directional,with instantaneous and time-delayed stages.
Earth-fault(ground fault)protection:This can include non-directional,directional,sensitive earth-fault(SEF),and transient-measuring earth-fault protection,suitable for different network grounding types(isolated,resistance-earthed,compensated,solidly-earthed).
Voltage protection:Overvoltage and undervoltage.
Frequency protection.
Thermal overload protection for feeder cables.
Breaker failure protection.
Often includes advanced functions like high impedance fault(HIZ)detection and arc-fault protection for enhanced safety and reduced downtime.
Integrated Control and Monitoring:
Control functionality for circuit breakers and other associated feeder devices,accessible locally via the Human Machine Interface(HMI)or remotely.
Extensive measurement capabilities for electrical quantities such as current,voltage,power,energy,frequency,power factor,and power quality parameters.
Event and disturbance recording with high sampling frequencies and extended record lengths,crucial for detailed fault analysis.
Comprehensive self-supervision and diagnostic functions to monitor the relay’s hardware,software,and communication,enhancing operational availability.
Advanced Communication:
Designed to fully leverage the IEC 61850 standard(including Editions 1 and 2,GOOSE messaging,and IEC 61850-9-2 LE for process bus applications),enabling seamless interoperability within substation automation systems.
Supports redundant communication protocols like HSR(High-availability Seamless Redundancy)and PRP(Parallel Redundancy Protocol)for increased system reliability.
Includes IEEE 1588 v2(PTP)for high-accuracy time synchronization.
Supports common legacy protocols such as Modbus,DNP3,and IEC 60870-5-103.Profibus DPV1 can also be supported via an external adapter.
User-Friendly Design:
Features a large,easy-to-read graphical LCD display for single-line diagrams and local access to settings and measurements.
Withdrawable plug-in unit design for fast installation,commissioning,and replacement.
Comes with ready-made standard configurations for quicker setup,with flexible tailoring capabilities via ABB’s PCM600 Protection and Control IED Manager software.
Supports creating multi-layer logic functions using various logical elements.
Robust Construction:Built to withstand the harsh conditions of substation and industrial environments.
